Getting Started
1 Introduction
1.1 CC3100MOD BOOST
Introducing the CC3100MOD Booster pack compatible with all TI Launchpads for adding
WIFI capability to embedded systems.
The CC3100MODBOOST Booster Pack is an easy-to-use evaluation module for the
CC3100 WIFI device. It contains everything needed to start developing a WIFI solution on
TI Launchpad. This board is also designed to interface with another board named
CC3100EMUBOOST (FTDI based Emulation and debug board) to provide an interface to
the PC for development using SimpleLink™ Studio (TI provided application and source
code to develop WIFI based software on a PC)
The CC3100MOD module integrates the complete RF, digital baseband, and power
management needed to provide WIFI access to any embedded system using a 8,16 ot 32
bit Microcontrollers.
Rapid prototyping is a snap thanks to the 40-pin headers and a wide variety of
Launchpads available. These connectors provide stackability to ensure that other
booster-packs like Audio, LCD, sensors etc. can be mounted on top or bottom of this
booster-pack.
1.2 CC3100MOD Module
The CC3100MOD module is a second-generation SimpleLink™ Wi-Fi self-contained
network processor module that dramatically simplifies the implementation of Internet
connectivity. The CC3100MOD module is an ideal solution for embedded applications
using low-cost and low-power microcontrollers with reduced board space and faster
development times.
Fully integrated module with serial flash, Crystal and RF filter. Only needs power
supply and a serial interface to operate.
802.11 b/g/n Station With Fully Integrated Radio, Baseband, and MAC
802.11 Transceiver Mode
IPv4 TCP/IP Stack
8 Simultaneous TCP, UDP, or RAW Sockets
ARP, ICMP, DHCP, DNS, mDNS
TLS 1.2/SSL 3.0 With On-Chip Accelerators
Throughput UDP: 16 Mbps, TCP: 12 Mbps
Interfaces With 8-, 16-, and 32-bit MCU over an SPI Interface with up to 24-MHz

Note :
All signals are 3.3V COMS logic levels and is referred w.r.t. CC3100MOD. For e.g.
UART1_TX is an output from the CC3100MOD.
For the SPI lines, the CC3100MOD always acts like a slave.
2.4 Power
The board is designed to accept power from a mated Launchpad or from the
CC3100EMUBOOST board. Some of the launchpads are not capable of sourcing the
peak current requirements of the WIFI. In such a case the USB connector on the
CC3100MODBOOST can be used to aid the peak current. The use of schottky diodes
ensure that the load sharing happens between the USB connectors on the Launchpad
and the Boosterpack without any board modifications.
Also the 3.3V power can be sourced from the Launchpad or from the 3.3V LDO on the
board. This is done by using the jumper J8. In the case where the Launchpad is not able
to source the 3.3V upto 350mA, then the J8 needs to be configured to work from the on-
board LDO
2.4.1 Power from the Launchpad or CC3100EMUBOOST
The most common scenario will be to power the CC3100MODBOOST from the mated
Launchpad. In this case the Launchpad provides 3.3V to the Booster-pack for its
operation. In addition to the 3.3V the Launchpad provides a 5V from the USB which is
used to drive a 3.3V LDO on the Booster-pack. This LDO sources the 3.3V used for the
top die flash used on development models.
